Answer:
LCL = 59.26 to two decimal places
Step-by-step explanation:
Here, we want to estimate the LCL of the population mean with 90% confidence
We proceed as follows;
Given alpha = 0.1, then Z(0.05)=1.645 (from standard normal table), s = 15
Mathematically;
LCL =x_bar -Z*s/√( n)= 62 - (1.645 * 15)/√81
LCL = 62- (24.675)/9 = 59.2583
LCL = 59.26 to two decimal places
Answer:
You use PEMDAS.
Step-by-step explanation:
If you dont know what that is, its the process used for long multistep equations like that : Parenthesis, Exponents, Multiplication, Division, Addition, then Subtraction. You solve all of those in order (if they are included in the problem). So for this you would solve one side of the inequality sign first using this order, then the other side and BAM! you've solved this problem.

Step-by-step explanation:
I don't know how to explain other than doing the math of (x*5)/2=16
Answer:
Y= 20x+35
Step-by-step explanation
This is the eqaution, because the amount of hours he works is x and the phone call are an added plus. Add them together and youll get y
